The Doctor and his companions beam down to Earth from the Nerva space station. It's not long before they encounter the crew of a crashed ship and the Sontaran warrior who's been hunting them. At only two episodes in length,
The Sontaran Experiment is one of the shorter serials in
Doctor Who's classic run. The fact that it was shot entirely on location also sets it apart from other stories. The plot is pretty thin, it was apparently supposed to be part of
The Ark in Space originally. Also, the choice to bring back the Sontarans was due to the fact that they could save money on the production by reusing the Linx's costume from
The Time Warrior. Tom Baker broke his collarbone during filming and there are some scenes in the second episode where he is clearly attempting to hide that his arm is in a sling.
Rating: This is extremely interesting%
